1. Safety information

IM-P133-65 CMGT Issue 2 3
1.4 Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline at some previous time.
Consider: flammable materials, substances hazardous to health, extremes of temperature.
1.5 Hazardous environment around the product
Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases, extremes of
temperature, hot surfaces, fire hazard (e.g. during welding), excessive noise, moving machinery.
1.6 The system
Consider the effect on the complete system of the work proposed. Will any proposed action (e.g.
closing isolation valves, electrical isolation) put any other part of the system or any personnel at risk?
Dangers might include isolation of vents or protective devices or the rendering ineffective of controls
or alarms. Ensure isolation valves are turned on and off in a gradual way to avoid system shocks.
1.7 Pressure systems
Ensure that any pressure is isolated and safely vented to atmospheric pressure. Consider double
isolation (double block and bleed) and the locking or labelling of closed valves. Do not assume
that the system has depressurised even when the pressure gauge indicates zero.
1.8 Temperature
Allow time for temperature to normalise after isolation to avoid danger of burns.
If parts made from PTFE have been subjected to a temperature approaching 260 °C (500 °F) or
higher, they will give off toxic fumes, which if inhaled are likely to cause temporary discomfort.
It is essential for a no smoking role to be enforced in all areas where PTFE is stored, handled or
processed as persons inhaling the fumes from burning tabacco contaminated with PTFE particles
can develop 'polymer fume fever'.
1.9 Tools and consumables
Before starting work ensure that you have suitable tools and/or consumables
available. Use only genuine Spirax Sarco replacement parts.
1.10 Protective clothing
Consider whether you and/or others in the vicinity require any protective clothing to protect against
the hazards of, for example, chemicals, high/low temperature, radiation, noise, falling objects, and
dangers to eyes and face.
1.11 Permits to work
All work must be carried out or be supervised by a suitably competent person.
Installation and operating personnel should be trained in the correct use of the product according
to the Installation and Maintenance Instructions.
Where a formal 'permit to work' system is in force it must be complied with. Where there is no such
system, it is recommended that a responsible person should know what work is going on and, where
necessary, arrange to have an assistant whose primary responsibility is safety.
Post 'warning notices' if necessary.

2.1 General description
The full bore two-piece body ball valves that are covered in this document have a floating ball as standard
and are produced in accordance with API 6D. They have been designed for use as isolating valves, not
control valves.
ISO mounting
As standard, all the valves in this document have an integral ISO body mounting which allows the valve to
be automated without losing seal integrity, as the body does not require disassembly. Manual to remote
control may therefore be easily accomplished by fitting a BVA300 series pneumatic actuator available from
Spirax Sarco. For further details contact Spirax Sarco.
Available types and applications
M33F2 ISO Has an API 607 firesafe design, zinc plated carbon steel body and PDR 0.8 seats (for
high temperatures)
M33F3 ISO Has an API 607 firesafe design, stainless steel body and PDR 0.8 seats (for high
temperatures)
API 607 firesafe design - In normal working conditions, the ball rests against two PDR
0.8 seats ensuring total closure. When the valve is submitted to temperature above the
limits the seats can withstand, the seat becomes deformed and renders to extrusion. When
the seats have been totally destroyed, the ball will come to rest firmly against the metal
seat in the cap, producing a metal-to-metal closing. This secondary seat in the valve cap
ensures the valve will operate to international API 607 standards.
Applications
Designed for use with the majority of industrial fluids on applications,
which include steam, condensate, water, oil, gases, and other fluids
within its operating range.
M33S2 ISO Zinc plated carbon steel body and PDR 0.8 seats (for high temperatures)
M33S3 ISO Stainless steel body and PDR 0.8 seats (for high temperatures)

Note: Before actioning any installation observe the 'Safety information' in Section 1.
Although the valve has great structural integrity, severe misalignment and/or the pulling effect of incorrect
pipe length will have a detrimental effect on the valve and must be avoided. Particular attention should be
paid to correct pipe alignment such that the inlet pipework and valve are all on the same axis.
Valves are for on/off applications and may be operated manually.
Wherever practicable, valves should be installed where there is adequate space available so that they can
be conveniently operated and maintained.
Before installing a valve, check to ensure that size, pressure rating, materials of construction, end connections,
etc. are suitable for the service conditions of the particular application.
Care must be taken to ensure that all dirt which may have accumulated in the valve during storage is removed
before installation, maintain cleanliness during installation since the introduction of dirt can result in damage
to the valve seats and operating mechanism.
To minimise the danger of abrasive particles damaging the seats, pipeline strainers should be fitted upstream
of the valves.
Install the valve with the handle in a suitable position. The preferred position is with the spindle vertical. The
valve can be installed in any position for gas service (see Figure 3 below).
When used on steam services:
1. Fit a trapped drain pocket upstream of the valve.
2. Open valve slowly to prevent the risk of waterhammer damage.
Fig. 3 Correct installation for gas service
Do not mount the valve upside down
for liquid service (Figure 2).
Fig. 2 Incorrect installation for
liquid service
Valves should be installed into the
pipeline in the fully closed position.
Always open valves slowly to avoid
system shocks.
3. Installation

IM-P133-65 CMGT Issue 2 9
After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms
or protective devices.
The valve is operated manually by a handle. Special care must be taken to ensure that the movement is
made in the correct direction.
The valve can be used as an on/off valve, and can be operated fully open, or fully closed.

Note: Before actioning any maintenance programme observe the 'Safety information' in Section 1.
6.1 General information
As with all mechanical devices, regular maintenance is the most efficient means of ensuring continued
operational efficiency.
Regular scheduled inspection of all valves is essential, especially on valves which are operated only
occasionally.
6.2 General maintenance
Isolate the unit - Before removing the M33 ISO ball valve from the pipeline to action any maintenance work,
isolate it both upstream and downstream and wait for the unit to reach ambient temperature before handling.
The complete body assembly can then be removed and any new parts fitted - See Section 7.
6.3 How to replace the stem seats:
-Remove the ball valve from the pipeline observing the 'Safety information' in Section 1.
Warning: Isolate the ball valve both upstream and downstream and wait for the unit to reach ambient
temperature before handling.
-Remove the nuts (20) from the studs (19) and split the main body (1) from the insert (2).
-Remove the seats (4) and the ball (3).
-Withdraw the stem (6) and replace the lower stem seal (7) and the 'O' ring (8).
-Reassemble the unit using a new body gasket (5). The nuts and studs (19, 20) and gland nut (13) should
be tightened to the recommended torque, see Table 1, page 12.
Please note - When the seats and lower stem seal have been replaced and the valve has been reassembled
it is advisable to conduct a cold hydraulic test to the valve body as follows:
-ASME 150 28.5 bar g (410 psi g)
-ASME 300 76.5 bar g (1010 psi g)
It is also advisable to conduct a seat leakage test using compressed air at 7 bar g (101 psi g).
After 24 hours in service, retighten nuts (20 and 13) and check for leaks.
